To a/Z whom, it may concern.'

Be it known that I, CHARLES F. SMITH, a citizen of the United States,residing at New Britain, in the county of Hartford and State ofConnecticut, have invented certain new and useful Improvements inMeat-Cutters, of which the following is a specification.

My invention relates to improvements in meat-cutters; and the objects ofmy invention are simplicity and economy in construction andefficiency inuse.

In the accompanying drawings, Figure l is a central vertical section ofthemain portions of my meat-cutter with some of the parts in elevation,the plane of section being indicated by the line Je :0, Fig. 2. Fig. 2is an end View of the case and forcer, the knives and clamping-ringbeing removed. Fig. 3 is a plan view of the knives or cutters thatbelong on the delivery end of the forcer, together with a portion of theforcer. Fig. L is a side View of the compound knife, showing the outerside, which works against the perforated plate. Fig. 5 is a like View ofthe reverse side of the said compound knife. Fig. 5%,- is a sectionalview of the same on the line y y of Fig. 5. Fig. 6 is a side view of theperforated plate. Fig. 7 is an end view showing the delivery end of theforcer in a modified form. Fig. 8 is a side view of the knives for saidmodification, showing the outer side. Fig. 9 is a plan View of the same.Fig. l0 is a side viewishowing the outer side of the inner one of thesaid knives.

The forcer A is mainly of an ordinary form, the crank end having ajournal or shaft portion 8, the outer end of which, that receives thecrank, being represented as broken off. The delivery end of the forcerhas a short shaft or journal 9 and a driving portionlO of an angularform. The body of the forcer has the ordinary screw form, composed ofthe main thread 1l and two additional threads ribs, and I prefer toemploy spiral ribs 15 for the main portion of the case, with shortterminal rib portions 16 arranged to extend longitudinally of the caseat the delivery end. The case is mainly of a cylindrical form, butflares outwardly on an abrupt taper 17 at the delivery end,the spacebetween the feeding-ribs throughout the whole length of the caseconforming substantially to the exterior form of the case, while thetops of all the ribs in the case Afollow the cylindrical form of theforcer from end to end of the interior bore of the case so far as theribs extend. This makes the terminal portions 16 of the ribs very deepor high at their outer ends, as shown, a little more than three timesthe depth of the spiral ribs 15 in the main body of the case. The endsof these terminal portions are faced off, preferably at right angles tothe axis of the case, to form cutting-faces for acting in connectionwith the knife hereinafter described. -Adjacent to the end portions 16of the ribs there is a short cylindrical chamber 18 for the knives torotate in, and outside of that a larger cylindrical portion 19 toreceive the stationary cutter 20, which, as shown, is in the form of aperforated plate. The case is provided with a fixed pin 2l and the edgeof the perforated plate with a notch or recess 22 to receive the saidpin or with other ordinary means to prevent the perforated plate fromrotating. The case at the delivery end is provided-ovali an externalscrewthread 23 to receive the nternallyfthreaded clam ping-ring M -,thatholds the perforated plate in place and presses the plate against theknife acting in connection therewith.

In the preferred form I make an integral compound knife-that is to say,what prac` tically constitutes two different knives or two sets ofknife-edges made in one and the same piece on a common body portion. Onthat side of the hub 25 that faces the forcer there is an angulardriving-socket 26, that fits on the driving portion lOQof the forcer,and leading from the said socket to the opposite side of the hub thereisa round hole that substantially ts the journal 9 on the end of theforcer, so that this compound knife cannot IOC whereby the outer knifeor knife-edges 27 K in number, extend from the extreme outer ends of theknifeblades tothe hub 25, into which they merge. J ust in front of theinner ends of these edges the hub is recessed or cut away, as at 29, toa depth which brings the bottom of the recess at a point a little insidethe inner faces of the feeding-ribs and inside the tops of the threadsof the screw-forcer to permit the meat to flow more readily than itwould if all of the meat were forced outwardly beyond the periphery ofthe forcer. Although the hub is recessed, as at 29, it is large enoughas to its major portion Ato extend outwardly and bear for a shortdistance on the end faces of the cutting-ribs 16, or, in other words,said hubis in the main a little larger than the bore of the case at theinner side of the feeding-ribs. Theknife or knife-edges 27 are set backfrom the edges 28,face the perforated plate,'against which theycut,andextend inwardly much farther-than the said edges 28 and preferably tothe central hole orjournal-bearingr on that side of the hub, the saidedges 27 projecting for- Wardly from the knife-arms on the broad side ofthe hub, so that' a clear space or chamber is formed between the cuttingends of the ribs on the case and the perforated plate, whereby the meatmay flow outwardly beyond the outermost inner walls of the case and atthe same time inwardly to a point adjacent to central hole orjournal-bearing in the perforated plate.' The outer limits of theperforations in the plate'20 are indicated by broken lines in Fig. l.The shape of the knife-blades in end view at their outer ends is clearlyshown in Figs. 3 and 5%. When the forcerhastwo short threads, itpresents the form-of a modified triangle in` end view, as shown in Fig.2, the grooves between the threads extending to the delivery end of theforcer, although quite shallow at the said end; In the modication shownin Figs. 7 to lO, inclusive, I give only one short'thread to the forcerA', which terminates diagonally opposite themrft'i thread, as shown inFig. 7. form'thsamc journal or shaft 9 at the outer end and employtwdahvgulardrivingportions 10 and 10b in dierent'sizes. The two knivesor two sets of knifeedges 27a and 28a are formed in two separate pieces.The knife 28,a has only two knife-edges arranged diagonally opposite tocorrespond with the terminal ends of the two threads on the forcer, andits hub 25a has an angular socket 26, Fig. 10, to fit the angulardriving portion l0" of the forcer. Its hub may also be recessed, as at29, if desired. It is also beveled or chamfered olfon its outer face topermit the material'passing it to work inwardly; but I make two breaks30 in this bevel for the back of two of the blades that carry the edges2.7a to `rest upon. This outer knife 27a has four blades, and its hub 3lhas an angular socket '34, that fits the driving portion 10b. Theseknives or two sets of knife-edges, like the extend inwardly so nearly tothe center of the perforated plate as do the knife-edges 27 trstdescribed. By reason of the angular form of the driving portions 10a lObin two sizes and corresponding sockets in the knife-hubs it isimpossible to wrongly assemble these knives. The series of knife-edgesarrangedin two sets in one piece or in two separate pieces areconsidered as equivalent-s, excepting in cases where the integrality ofthe two sets is particularly mentioned, and the numberin each set isimmaterial, solongas there is at least one knife-edge in each set.

In both constructions as the meat reaches the enlarged space between theribs'at the flaring end of the case it spreads outwardly and fills theoutwardly-tiaringspaces between vthe forcer and within the diameter ofthat side of the hub that bears against thel ribs. The constructionissimple, while the machine is efficient. The clamping-ring for theperforated plate acts to adjust one set of knifeedges properly againstthe face of the perforated plate and the other set'againstthe ends ofthe terminalI portion ot the ribs.

Itis apparent that some changes from the specic construction hereindisclosed maybe madeand therefore I do not wish to be understoodaslimiting myself to the precise form of construction shownand described,but desire the liberty to make such changesin working my invention Vasmay fairly come within the spirit and scope of the same.

claim as my invention- I l. The combination of the case having internalribs that terminate in end cutting-faces,

with the forcer, a knife-edge rotating with the saidforcer, extendingoutwardly beyond the periphery of the said forcer and across the ends ofthe said ribs against whichit end of the "case and having its cuttingarea extending both outwardly and inwardly to said knife-edges to thesaid stationary cutter and also to she end cutting-faces of the ribs. 2.The combination of the case having a IOC IIO

cuts, a stationary cutter mounted in the outer cylindrical body with anoutwardly-enlarged delivery end, and internal ribs extending over thesaid cylindrical and enlarged portion with the tops of the ribs forminga cylindrical bore throughout the length of the interiorly-ribbedportion of the said case, the ends of the said ribs havingcutting-faces, with asubstantially cylindrical screw-forcer, a knife-edge rotating with the said forcer at the end thereof and acting onthe said end faces of the said ribs, a stationary cutter mounted in thedelivery end of the said case and havingacutting area that extends bothinside and outside the diameter of the said forcer, and a knife-edgerotating with the forcer and acting on the inner face of the saidstationary cutter.

3. The combination of the case having interior ribs, the ends of whichform cuttingfaces, with a rotary forcer, a knife-edge rotating with thesaid forcer and extending across the said cutting-faces, a hub for thesaid knife-edge mainly of a larger diameter than the smallest innerdiameter of the case at the said cutting-faces, a stationary cuttermounted in the delivery end of the said case, and a knife-edge acting onthe inner face of the said stationary cutter, the said knife-edgeextending inwardly to a point inside of the inner diameter of the saidend cutting-faces of the ribs, whereby the meatis mainly forced7 iirstoutwardly beyond the diameter of the forcer, and then part of itpermitted to iiow inwardly within the diameter of the forcer'.

4. The combination of a case having interior ribs the ends of which formcutting-faces, with a rotary forcer, a stationary cutter mounted in theend of the said case and knifeedges rotating with the forcer and actingon the said stationary cutter and end cuttingfaces of the said ribs, thecutting area of the said stationary cutter and coacting knifeedgesextending both outside and inside the inner diameter of the said endcutting-faces of the said ribs.

5*. The combination of a case havinginternal feeding-ribs with thespaces between. the said ribs enlarged outwardly at the delivery end soas to be of a greater depth at the ends of the said ribs than at anyother portion of the case, the said ribs having cutting-faces at theirends, with a forcer rotating within the ribbed portion of the said caseand having grooves that extend through to its delivery end, and a cutterhaving a hub mounted on the endv of the said forcer to rotate therewithand act upon the ends of the said ribs,`
